WINDOW OR DOOR BLIND.

SPECIFICATION forming part of Letters Patent No. 465,098, dated December15, 1891.

Application filed October 31, 1890. Serial No. 369,887. (No model.)

To all whom it may concern.-

Be it known thatI, JOHN A. MAULE, a citizen of the United States,residing at Lafayette, in the county of Tippecanoe and State of Indiana,have invented certain new and useful Improvements in lVindow and DoorBlinds; and Ido hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to that class of shutters that is provided withmovable slats operated from the inside of the house by means of amovable rod having suitable connection with the movable slats.

The object of my invention is to improve upon the construction of thatclass of devices; and to that end the nature of the invention consistsin constructions and combinations, all as will hereinafter be set forthin the specification, and pointed out in the claims, reference being hadto the accompanying drawings, in which- Figure lrepresents a frontelevation with slats open; Fig. 2, a front elevation with the slatsclosed and partly broken away to show slat in the slots; Fig. 3, a sideview of the bar; Fig. 4, a section showing the bar, reccsses,adjusting-nut, and other parts; and Fig. 5, an end view'of one of theslats.

A represents the frame of a shutter, and A the slats. In one side of theframe a groove a is formed, and in this groove is placed a rod or bar a,of less length than the groove, so that said bar can be moved up or downin said groove, for a purpose hereinafter explained. The bar may be ofany desired width-4'. e, of a width equal to the depth of groove a, orless width--and provided with a projection a for a stud a that extendsthrough a slot a formed longitudinally in the frame and provided with atransverse passage a toward the slats A. Before the slats are put in theframe the bar a is inserted in the groove. a, the stud a entering theslot a through the transverse passage a and is held therein by movingthe'bar longitudinally until the stud of is moved past the transversepassage a, where it is held in place primarily by a stop-plate a,secured to the stud and of sufficient length to allow the stud to have alimited movement, the scope of which is regulated by the ends of therecess a formed in the face of the shutter and concealed from view by acap or cover a secured to the frame and having an opening a for the studa to project through. The projecting end of the stud is screw-threadedand receives an interiorly-screw-threaded knob a for raising andlowering the bar a and, when desired, locking the bar in any desiredposition by screwing the knob down against the cap or cover (1,8, whichhas more or less resiliency. The bar is also provided with aseries ofpins a, which project into the opening of the frame and, as willhereinafter be explained, into the slats. The slats are hinged at theends of the upper edges to the frame by means of eyes b and staples b,the former being on the slats, and the staples inserted through the eyesinto the frame, so that by pulling out one or both of the staples theslat can be removed from the frame. The end of each slat next to the bara is provided with a longitudinal recess b into which the pins (0 one toeach slat, is inserted, so that whenthe bar a is moved up or down thepins will slide in said recesses and cause the slats to move outwardlyand upwardly or inward and downward, as the case might be, to open orclose the spaces between the slats, and when the pins have been moved tothe outer or lower end of the recesses the slats are locked in place, sothat they cannot be moved except by lifting the bar a, as the slats, byreason of their being pivoted at their upper edges and held down neartheir lower edges by the pins, offer practically no leverage to any oneprying under the lower edge thereof.

The operation of the device is as follows: If the slats have been letdown or closed and it is desired to open them, the rod or bar a. israised by means of the knob a until the slats have been moved thedesired distance, this movement being accomplished by the pins 61,sliding in the recesses 0 which are parallel with one or both sides ofthe slats, and as .the bar 0: moves upward the pin moves in the recessand lifts the outer end of the slats and discloses the spaces betweenthem. Theslats can be held in that position by screwing the knob downupon thecap or cover. The slats are let down by a reverse movement ofthe knob, which, it moved down to the fullest eX- tent, carries the pinson the bar a to the lowermost point in the recesses U The recesses Z1may be formed in the ends of the slats, or they may be formed in metaland attached to the ends of the slats, in which the eyes I) may beformed integral with the metal.

What I claim as new is 1. In a shutter, the combination of the frame,bar a, adapted to move up and down within the frame and having pinsprojecting beyond said frame, slats extending from end to end of theframe and pivoted thereto at the ends of their upper edges, the ends ofthe slats adjacent to bar at having a longitudinal slot b within whichthe pins of said bar move, as set forth.

2. In a shutter, the combination of a frame having alongi.tudinalgroove,a longitudinal slot, and a recess around said slot,at barhaving a stud projecting through said slot and having a stop-platein said recess, a bar a in said groove having pins a, and slats pivotedto said frame and having recesses in their ends for engagement with thepins on bar a, substantially as described and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

- JOHN A. MAULE.
